PROCESS OF MEMORY

Computer memory is any physical device capable of storing information temporarily or permanently.

For example, Random Access Memory (RAM), is a volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware

The memory of the computer is divided into to categories:

1. Primary Memory

1. Secondary Memory

Primary Memory:- Main memory of the computer. CPU

can directly read or write on this memory. It is fixed on the

motherboard of the computer.

1. RAM (Random Access Memory):-is a temporary memory.

Information lost if

computer turn off.

2. ROM(Read Only Memory):-Information stored

permanent in nature, it holds data if the computer switch off.

It cannot overwritten by the computer.

2. Secondary memory:- This memory is permanent in nature.It holds the information till

we erase it.

Different types of secondary storage devices are:

1. Hard Disc capacity (Unlimited)

2. Compact Disc (upto 700 MB)

3. DVD (upto 4.7 GB)

4. Pen Drive (upto 2 TB)

5. Blue Ray disc upto 25 GB)

HARD DISC (UNLIMITED CAPACITY)

COMPACT DISC (700 MB)

DVD (DIGITAL VERSATILE DISC) (4.7 GB)

PEN DRIVE (2 TB)

BLUE RAY DISC (25 GB)
